1. A method for operating a system comprising a first interface, a second interface and a computation unit coupled to the first and second interfaces, the method comprising:
receiving at the first interface input data, wherein the input data comprises data from electrical impedance spectroscopy carried out on a solar cell comprising perovskite material or parts thereof, with the electrical impedance spectroscopy being carried out inline during a manufacturing process of the solar cell,
operating the computation unit to apply a trained function to the input data, wherein output data is generated,
providing at the second interface the output data, wherein the output data comprises a performance value of the solar cell, and
monitoring the manufacturing process of the solar cell based on the output data.
